PANORMIC CAM ERA.

SPECIFICATION forming part of Letters Patent No. 671,1 54, dated .April 2, 1901.

Application filed August ll, 1899. Serial No. '726,847- lNo model.)

T MZ whom, 7125 may concern:

Be it known that l, PETER N. ANG-STEEN, of Burlington, in the county of Racine and State of Visconsin, have invented certain new and useful Improvements in Panoramic Cameras; and I do hereby declare that the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to cameras, and refers more particularly to that class of cameras, known as panoramic cameras, wherein the 'film is held in a suitable holder within the camera-case and the lens is carried by a pivotally-mounted lens-holder which is springactnated, so that when released the lens will turn in the arc of a circle and expose agiven amount of the film.

One of the objects of the present invention is to provide a panoramic camera with means for holding the swinging lens in a central position in order to expose a sensitized plate in lieu of a film and without increasingthe fecal length of the camera-case.

Another object of the invention is to provide means for automatically closing the lensholder or shutting off the light at the desired time in the swing or movement thereof.

Another object of the invention is to produce a device for regulating the amount of film to be exposed for a picture and to regnlate the extent of the throw or swing of the lens for that purpose.

Another object of the invention is to provide means for mounting a finder so as to move synchronously with said devicefor regnlating the t-hrow or swing of the lens, whereby the finder will locate only such portion of the landscape or picture as it is desired to take, and thereby facilitating the work of the photographer. f

Another object of the invention is to provide a punch whereby may be indicated on the film the dividing-line between portions thereof that have been subjected to different exposures.

Another object of the invention is to provide a suitable friction device upon the receiving-hlm spool or holder to keep the film in proper position iu its guide or way, and

which friction device shall not tear, scratch, or otherwise injure the film.

Yet another object of the invention is to provide upon the outside of the case a suitable indicator so connected with the case that it will be operated synchronously with the receiving-film spool or holder, whereby to indicate precisely how much of a film has been exposed or has passed the exposed lield and been rolled up in said receiving-spool.

Another object is to combine in one camera a revoluble or swing lens and means for focusing said lens when and for a fixed or set exposure.

All these and other objects of my present invention will be more fully understood by examining the accompanying drawings and subjoined description thereof and will be more fully pointed out in the appended claims.

l/Vhile I have illustrated herein one practical embodiment of my invention, I do not desire to be limited to the precise details of construction set forth, since many modilications thereof may be used without departing from the spirit of my invention. I desire, therefore, my claims to be considered and to be construed broadly to include all such modifications.

In said drawings, Figure l is a top or plan View of the outside of a camera embodying my present invention. Fig. 2 is a transverse vertical sectional view of the same, enlarged,

taken upon the line 2 2 of Fig. l, the lens being centrally fixed and the film removed, whereby a set picture may be taken on a plate. Fig. 2 is a detail of the lens-locking device when plates are used in lieu of a filmstrip, taken on line 2 2 of Fig. Fig. 3 is a horizontal sectional View taken on line 3 8 of Fig. 2, but with the film-strip in position. Fig. 4 is an elevation showing the inside of a portion of the front of the camera, the view being taken in the direction indicated by the arrow in Fig. 3 to illustrate in full lines the initial and in dotted lines the final position of the lens-holder in taking a panoramic picture.

Fig. 1S is a section through another Vform of stop lor the lensholder and its connection with the supporting-plate. Fig. 1f) is a fragmentary rear elevation of a lens-holder, showing still another forni of shutter applied thereto, said lensholder being at the limit of its movement. Fig. 2U is a horizontal section taken on line 2O 2O ol Fig. 19. Fig. 21 is a cross-section through the lens-holder, showing the construction of the shutter. Fig. 22 is a crossseetion through said shutter. Figs. 23 and 2st illustrate another lneans for actuating the movable stop and Ender-supporting plate, said constructionbeing a modification of that shown in Fig. 11.

ln the drawings, A represents the top wall of the camera case or frame; A', the handle thereof; a, thebottom wall; d', the front wall; a2 a3, the two end walls," and d4 the back wall of said case. ln the back wall a4 is a hinged door a5, to permit access to the interior of the oase. An angle-door A2, hinged to the end wall d3, affords access to one corner of the case for a purpose hereinafter stated. Said doors are fastened by a common clasp, as shown in Fig. 3.

B represents the lens-holder as a whole, which is pivotally mounted upon oppositelydirected spindles l), as herein shown. The

lens-holder B projects through a suitable opening in a flexible front B of the cloth or other suitable material, the margins of which are secured between a shoulder d upon the front wall d' and a molding al, said shoulder d terminating and marking the margin of an opening as through the front wall (t, which, but for the ilexible front l', would permit free access to the interior of the eamera-case.

C is a spool revolubly mounted in a familiar manner in the front right-hand corner ol' the box, as shown in Fig. 3, and upon which is wound any suitable or desirable quantity of sensitized tllmc. Anotherspool C is similarly mounted in the corresponding opposite corner of the box, as shown in Fig. 3, and the film is passed from one spool to the other in the manner hereinafter described, tirst passing` over rollers c', positioned near the spools C C'. A. curved groove extends from one spool tothe other, the axis ot the lens-holder spindles b being the center of the circle. Said groove is lettered c2 in the drawings and is formed not only in the lower or bottom wall a, but in the upper or top wall A.. Said grooves c2 are herein shown as formed between separate curved pieces attached to said upper and lower walls. The means oi supporting and driving the lilm-strip iorms no part of the present invention, and being readily oomprehended from the drawings, Figs. 2 and 3, will not be herein further rel'errcd to. It has been found, however, that in passing the iilm from one spindle to another the film is likely to be scratched or otherwise injured, and to prevent this l train the film over antit'riction-rollers c, as before stated.

C2 designates a spring-pressed pivot-plate, which, acting under the influence ot' a spring e3, presses against the Film-strip upon the spool C and maintains a proper tension upon the iilm. By this simple arrangement l [ind that the hlm-strip is wound and un'wonnd and passed from one spool to the other without any injury whatever'.

I will now refer more particularly to Figs. 2, 3, 4, 5, (i, and 10 in describing the means for swinging the lens-holder, for stoppingit in any desired point in its movement', and ["or automatically closing the interior shutter at the desired time in the movement thereof. It will be understood that if a maximum posure O'll iilin is to be made-call it, for example, twelve inches-the lens-holder l will be swung upon its spindle i) into a position opposite that shown in Figs. 3 and 1t, or through an ar'cof approximately one hundred and eighty degrees, while ii`-an exposure is desired ot', say, six inches, or one-half the maximum, the lens-holder will be swung from the position illustrated in Fig. to that illust-rated in Fig. 10. The said spindles I) are attached to the central tubular section l52 of the lens-holder and to which the flexible closure B is secured. Telescoping within said tubular section B2 is the lront section of the holder B3. Said section l:s is provided lOO lOS

IIO

tsr/1,154

with a radially-projecting pin b', which latter is adapted to enter and engage an L.- shaped angle or bayonet-catch slot h2, ext-ending inwardly from the front margin or edge of the tubular member B2. By means ot' this connection the outer section B3 and the central section B2 are removably locked together when the camera is to be used as a panoramic camera. When it is desired to expose a plate instead of a tilin the lens may be focused by iirst rotating the section B3 until the pin b/ is opposite the longitudinal portion of the slot b2 and then sliding said section in- .wardly or outwardly, as required, the telescoping` parts fitting with a reasonable amount ot' friction for this purpose. When the camera is to be used as an ordinary camera, the innermost section F', which has sliding detachable engagement with the central section of said holder, may be removed and an outer section carrying the usual automatic or quick-action shutter, and a different lens, if desired, substituted for the outer section B3.

Around the upper one of the spindles i) is a spring D, the lower end of which is fixed to the central section B2 of the lens-holder, and the upper end of which is secured at d, to a rotative sleeve D, with which the upperend of the spindle b has rotative engagement. To the upper end of this sleeve D' is a fixed gear d', herein shown as made integral with the sleeve and located in a suitable recess d2 in the top wall A. Said pinion meshes with a worm-gear d3 upon a spindle d, that projects laterally outwardly to the front of the camera-box and is provided outside of the box with a thumb-piece d5. Said spindle acts when rotated to rotate the sleeve and vary the tension of the spring D, and thereby vary the time required to swing the lens from its initial to its inal position and increase or decrease the time of exposure, as conditions may require. The lower spindle b has bearing at b2 in a suitable projection b4, projecting inwardly from the liront wall CV of the box, and said lower spindle is provided with a projecting arm B4', which arm engages the end of a spring-pressed lever B5, as more clearly shown in Fig. et, and by which it is held in its normal or initial position. Extending upwardly and through the wall of the box is a pin B, the lower end of which engages the other end ofthe lever B5. A spring if presses upwardly against the underside of the level-B5, so that said lever is normally in the substantially horizontal position indirated in Fig. et. Downward pressure on the rod B depresses the adjacent end of the lever B5 and raises the opposite end, and thereby releases the engagement of the lever B5 with the arm B4. so that the lens-holder may swing on its pivot under the infinence of its actuating-spring. An auxiliary spring D2 surrounds the lower spindle of the spindle l) and acts upon the lens-holder as does the spring D, but is not provided with any device for adjusting its tension.

The amount of swing or throw of the lensholder in order to expose the desired amount of film-surface is regulated by the following mechanism: Upon the top of the box is a plate E, having' a suitable index or graduated surface e, indicating the different positions at which the holder-stop may be located. E is a handle attached to a spindle e', the latter of which is longitudinally movable through a suitable opening er bearing in the top wall of the camerabox. Seen red to the handle E or the spindle e is an index-linger or pointer e2, carrying on its under side a small looking pin e3, which latter is adapted for engagement with locking-holes e4 in the plate E, arranged coneentrically to the axis of the spindle e and at the desired intervals. Secured to the lower end of the spindle e is a stoparin E2, the innerend of which carries a downwardly-projecting lug or pin e5. A pinion E3 is secured to the spindle c, above the arm E2, and a suit-able spiral spring El is interposed between the lower or under side et the top wall of the box and said pinion and arranged to exert a downward pressure on the spindle and move said pin eS into the aperture el and lock the stop-arm in any desired position. It the arm be set for any given amount of surface of ln'i-exposu re-say eight inches-and it is desired to set it for, say, fou r inches of exposure, the handle E is raised against the action of the spring E'L and then rotated until the index J2 points to the num` ber on the graduated plate E, and upon the handle being released the spring will force the locking-pin c2 into that one of the lockingholes e'l which corresponds with the desired number on the graduateiii plate.

The downwardly-projecting pin or stud er is adapted for engagement with a projection f on a swinging shutter F, v. hich latteris pivotally mounted n pon snitablearmsf", secured to the inner section F of the lens-holder. Said inner section, as shown more fully in Figs. S, si, and S, consists ot' a tubular cylin drie part f2, adapted for telescopic engagement with the inner portion of the central section B2 of the lens-holder, to which tubular part f2 is secured a part having approximately parallel side walls and flaring end wallsf". The sh utter F is so pivoted upon the inner section F that when it is swung backwardly, as indicated in Fig. 7, the rays of light may pass from the exterior of the camera and through the holder in to the interior of the box to the liltn in the direction indi* cated by the arrow in Fig. 7. iVhen said shutter F is swung to the position indicated by dotted lines in Fig. '7, it will completely close the opening in the holder and shut olf all light to the camera. When the lens is in its normal position, as indicated in full lines in Figs. 3 and Lt, the shutter F will be opened by reason of the fact that its outer or swingf ing end will be engaged by the margin of the wall a, surrounding the opening' therein. Nhen the lens is swung around on its spin- IOO dle to the end of its maximum throw, the arm thereof will engage projection a on the innerside of the front wall of the box and swing the shutter to its closing position, the stoparm being at this time swung out of the way of' said shutter-arm. When said stop-arm is set to stop said holder at an intermediate position, the projecting stud or pin e5 will engage said shutter-alan and swing the shutter to its closing position. When the shutter is closed, the engagement of the arm thereof with said pin c5 serves to arrest the movement of the lens-holder. Thus the pin ci serves the double purpose of arresting the swinging lens-holder and also of closing the shutter at the proper time. So far as the closing of the shutter intermediate the limits of movement of the holder is concerned it may obviously be effected without arresting the movement of the lens-holder, and said lens-holder may at each operation of' the caniera swing through its maximum throw.

A Vfamiliar implement, linown as a finder, has heretofore been used upon cameras. i have indicated suoli a device by the letter G in Fig. l, but will not describe its mec' aiiisin in detail. Suffice it to say that such a finder is removably secured to my camera by means of flanges J', engaging guide-grooves g', formed by turning up the margins of a rotative plate G. Said plate G is mounted upon a spindle g2, passing through 'the top wall of the (.'amera-box and carrying upon its lower inner end a gear-wheel G?. Motion is comn'iunicated to said gear-wheel G2 from the pinion E3, connected with the stop-arm spindle, through un intermediate gear-pinion g3, rotatably secured, as shown in Fig. il, or in any other suitable manner, to the inside of the top wall of the box. lnasniuch as the spindle e, on which the pinion E3 is mounted, is )rovided with a longitudinal movement, it will be desirable to make said intermediate pinion g3 of double the width of the pinion E3, so that the tooth of the latter will at all times be in engagement with the tooth of the pinion g3. Upon the other end of' the dialplate E or a similar gaduated plate is provided a second series of numbers corresponding with those shown at c, and an index finger or pointer gl extends outwardly from the plate Gf and cooperates with said numbers in a familiar inaniier. From this construction it will be manifest that when the handle .E of the stop-arm spindle is turned one way or the other, so as to bring the pin or stud c5 of' said arm into position for a given amount of' exposure, the finder G will be automatically turned at an angle suitable for indicating the saine amount of landscape, thus greatly facilitating the taking of an accurate picture.

ln using a continuous film in a camera it becomes desirable to indicate on the film the dividing-line between the different exposures in order that the film may be severed on such line in the dark or developing room. This is accomplished in my camera by means of a reciprocating punch which makes a small aperture in one edge of the film. The mechanism is illustrated more clearly in Figs. i, l2, and 13. Referring thereto, H designates a rotative spindle extending vertically through the top wall of the camera-box, to the upper end of which is secured a handle 7i, by which the spindle may be rotated from outside the box. 'llo the lower end of the spindle H is rigidly secured an arm h', connected at its outer or free end with a reciprocating bar h2, which has a bearing at 72,3 in an interior casing h1, which surrounds one of the film-spools C and extends at its inner end closely adjacent fo the film-strip just outside of the roller c', adjacent to the spool C. The forward end of the bar 7b2 is either suitably sharpened or provided with a cutter or punch, so that when the spindle H is pztrtially rotated longitudinal movement will be given to the bar 72,2 and a hole or aperture punched or cut through the upper edge of tno film c. Preferably this aperture will be made in that portion of the margin of the film that engages the upper guide-groove c2, so that it will not in an y way interfere with the field-namely, that portion of the film that has been exposed.

The spindles of the spools C C, upon which the film c is wound, project through the upper wall of the camera-box and are provided with thumb-pieces C3, as shown in Fig. l, by which they may be rotated and the film unwound from one and wound upon the other spool. ln order to determine just how far to wind the film after or before anv exposure of a given amount of film, l provide an automatic index device, as shown in Figs. l, l-f, and l5. Suchindex device consists of a graduated plate l, which corresponds to the plate E. .Vithin the camera-case and at therear left-hand corner, Fig. 3, is located a frictionwlieel l', so arranged as to extend slightly into the lower guide-groove ci, and thus be in Contact with the lower margin of' the film c, so that movement of the film will rotate said frictirm-wheel. Said wheel l.' is connected with a shaft or spindle t, which latter ex` tends upwardly and has bearing at its upper end in the top wall of the camera-box. Said spindle 1l carries on its upper end a pinion t', which meshes with a gear-wheel l2, mounted upon the lower end of the spindle i2. Said spindle E extends upwardly through the top wall of the box and through the index-plate l and is provided on its outer end with an index-finger t3. Said plate l will be graduated toindicate inches and fractions of' inches, and the disk l/ and pinion and wheel l2, respectively, will be so proportioned as to move the index-finger 'i3 from one index-mark to another when a given point on the film passes through a distance of one inchr lt will be seen, therefore, that by reference to the graduated plate li after the stop-arm has been adjusted the proper amount of film may be accurately and readily wound from one spool to the other, as

iig

the index-finger connected with said stop-arm IWill indicate the length of Film to be used,

and the index-hingen1S will indicate when the proper amount of lm has been wound off of one spool and onto the other.

As a matter of convenience merely T locate upon the top right-hand corner of the rear end of the camera-box, as shown in Fig. l, an indextinger i4, which is adapted for manual operation each time a picture is taken, the idea being that upon its dial 13 may bc kept a record of the tot-al amount of' film-exposures made from time to time, so that the operator can tell at a glance, knowing how much film he ought to start with, the precise amount of unexposed film left in his camera and available for use, if any.

One of the objects of my invention, as be fore stated, is to provide means whereby an ordinary sensitized plate may be exposed as well as a lm. For the purpose it will be necessary to locate thelens-holder B in a fixed position, preferably in a central position, as shown in Fig. 2. This is accomplished by first moving the stop-arm E2 entirely out of the way, and then, having disengaged the arm B4 from the spring-pressed lever B5 b y bringing the lens into the position indicated in said Fig. 2 or other desi red position,thelens-holder is then locked in such position by moving forward a slide J in the lower part of the camera-box into engagement with the arm B4 of said holder. This slide J is movably secured to the bottom wall a of the box by screws j, passing through suitable slots j in said slide. The guide J is provided with an upturned arm '72, having a slot in its upper margin It is in this slotj3 that the end of the arm B4 islocated when the lens holder B is in its central position, as indicated in Fig. 2. The inner section F of the lens-holder Bis at this time removed from the central section and the outer section B2 'focused in the manner before described or another'section having a different lens and a quick-acting shutter substituted therefor, as desired. The film c is also entirely removed.

The construction of the box is such as to provide a curved film-support K in vthe rear part. thereof, as shown in Fig. 3, which support forms really the back of the guide-groove c2. This support K is cut away in its part opposite to the lens to provide a space of suit able size for the plate to be exposed. ln rear of said central opening` is a suitable frame K. In the rear of said frame K is provided a second frame K2, between which and the frame K' is a plate-holder K2. Said fra-me K2 is a movable frame and is provided with flat springs K4, which tend to keep the Yframe in the position indicated in Fig. 2-to wit, to its position nearest the lens. The door ai being opened, the picture is presented upon a ground glass 7c, secured in the movable frame K2, and the lens B is focused accordingly. The plate-holder will be inserted into place and removed therefrom through the angledoor A2. When the plate-holder K3 is removed, the spring K"l will cause the frame K2 to move forward into its normal position, as indicated in Fig. 2.

The space L at the right-hand portion of the camera-box, located between the support K and the side z2 and closed by the door A2, may be used as a magazine and will be convenient for the purpose of storing several filmspools C. Ot' course before inserting or re` moving the plate-holder KS it will be necessary to temporarilyr remove one or more of the spools C from the magazine L.

The shutter instead of being located at the rear end of the lens-holder may be located between the inner and intermediate sections thereof, as shown in Figs. 1G and 17. Said figures also illustrate a modified form of shutter. As herein shown, M indicates the flaring` inner section of the lens-holder, which is attached by screws in to the intermediate section M', said inner section being provided with a flange m', which is adapted to engage a similar dange on the inner end of the intermediate section, and between which flanges the shutter is located. Said inner section is provided with an opening m2, through which the light passes when said opening` is unobstructed. M2 MS designate L-shaped shutter members which are pivoted to the flange m', on the opposite sides of the opening therein. The shutter member M2 is pivoted at its angle near one end of the opening and has its longer arm normally outside of and substantially parallel with one side margin of said opening, while the other shutter member is pivoted at the end of its shorter arm near the opposite end of said opening and with its longer arm normally outside of and substantially parallel with the other side margin of suoli opening. A link M'l is pivoted at one end to the shorter arm of the member M2 and at. its other end to the angle of the other arm. M5 designates a lever having the form of an annular plate or disk, as herein shown, which is pivoted to an extension m2 at the upper end of the fiange m by means of a pivot-pin m4. Said plate or lever is provided with a lug fm, which projects into the path of a stop o, which corresponds in function to the stop shown in the previouslydescribed figures. Said lever M5 is connected with the shorter arm of the shutter member M2 by a link in, which is pivoted at its opposite ends to said lever and arm. The annular plate or lever M is cut away on one side to provide two stop-surfaces m7 m7, which are adapted for engagement with a stop-pin mson the projection m2 and by means of which movement of said lever is limited in both directions. With this construction when the projection m5 enthe stop o in the movement of the lensholder it will act, through the action described, to move said shutter members together in an overlapping relation, and thereby prevent the light from passing through the opening m2. Suitable stops may be pro- TOO IOS

vided for engagement with the lug` at either limit of the holders movement.

In Figs. t6 and 18 is shown a modification of the adjustable stop for limiting the movement of the lens-holder and the means for actuating the same. As shown in said figures7 the upper lens-holder spindle l) Fits at its upper end within a sleeve O, which is attached to the lower end of a spindle O', which has bearing in a plate O2, attached to the upper wall of the box and projects outside of said box. O3 designates a sleeve which surrounds said sleeve O and the spindle h and which is of greater internal diameter than the external diameter of the spindle Z) and sleeve O. Said sleeve is attached in any convenient manner rigidly to the under side of the plate O2. Ol designates a pinion which is rotatively mounted on a reduced portion of said sleeve which is inside ot' the plate O2. O5 designates a disk rigidly attached to the said pinion and which also has rotative bearing on said reduced portion of said sleeve O3. Said disk corresponds with the stop-lever of the previously-desembed iigures and is provided with the stop lug or projection o, which extends into the path ot' the lug mi. P designates a finder-supporting plate located on the upper surface of the plate O2. Said plate is attached to and rotates with a gear-wheel O by means of a pin o', which has rotative bearing in said plate O2. OT designates an intermediate pinion or idler located between said pinion Ol and the gear-wheel OG, rotatively mounted on a suitable pin (not shown) attached to said plate O2. o2 designates a spring surrounding the said spi ndleb and the sleeve O and between the latterand the sleeve O3, said spring being attached at one end to the said sleeve O and at its other end to the spindle ZJ, whereby the tension of the spring may be varied by turning said sleeve with reference to the spindle. Means for turning said sleeve and adjusting the tension of said spring consists ol' a thimble 03, which lits over the portion of the outer end of the spindle O/ which projects beyond the plate O2. Said thimble is connected with the spindle by means of a nut 04, which has screw-threaded engagement with the extreme end of the spindle and tits within the upper end of the thimble, said nut being provided with a lug o5, which engages an internal groove oG in said thimble, whereby when the thimble is turned it will act through the nut to turn the said spindle, and thereby vary the tension of the spring` 02. Said thimble is locked in place by means of pins o7, attached to the inner end thereof and adapted to engage apertures in the upper or adjacent tace of the plate. Said pins are held normally in engagement with said apertures by means of a spring 0S, which is interposed between the nut oJ1 and an internal shoulder in the thimble 03. The provision of the slot or groove o(s in the thimble engaged bythe lug 05 permits said thimble to be lifted to disengage said pins o7 from the apertures in the plate 02, at which time said thimhle and spindle will be free to be rotated. This construction has the advantage of compactnoss, as it enables the disk 05 (which is in ei'fect a lever) to swing on an axis of oscillation coincident with the lens-holder spindle.

Next describing the construction of the shutter shown in Figs. 1.9, 20, 2l, and 2i', these parts are made as follows: rlhe lens-holder is made substantially as that shown in Fig. if, being rotatively mounted on the spindle l), which has bearing in the upper wall of the box or inclosure. The shutter consists of a tubular section R, which is rotatively mounted in the inner section of the holder in a vertical position just inside oi' the contracted opening oi' the flaring portion S ot' the holder S. Said tubular section is provided with a spindle s, which projects ou tside oi. the holder,and which spindle is provided at its outer end with an arm s, which is adapted for engagement with stops 'F T, connected with the upper wall ot' the box or inclosnre at either limit of the movement of the lens-holder and which is also adapted for engagement with an adjustable stop of any of the forms shown intermediate its limits of movement. Said shutter is provided with oppositely-arranged longitudinal oj enings r, as shown more clearly in Fig. 22, which when turned opposite to the contracted opening in the flaring portion S ol the lens-holder permits light lo pass therethrough. 'lhe walls oi said shutter on each side of said opening r are imperlorate, so that when said shutter is turned to bring said openings out of line with the opening in the lens-holder the imj')ertorate walls of the shutter will exclude light from the interior of the camera through said holder. Stop-pins s2 s2 are provided on the upper face ot the lensholder and are adapted to engage a stop-arm s3 on the Vspindle s and serve to limit the rotation of said shutter in both directions. It will be understood that the shutter will be in position to permit passage of light through the lens-holder when the stop-arm s3 is in engagement with one of the stop-pins s2 and to cxcludelight from said holder when said stoparm is in engagement with the other stop-pin. The construction or arrangement of the parts is such that the shutter will be rotated to exclude the light when the lens has reached the limit of its movement or is arrested in an intermediate position.

Next referring to the construction shown in Figs. 23 and 24, which illustrates the connections between the stop-spindle and the finder-spindle, said parts are made as follows: U designates a spindle which carries at its lower end an adjustable stop-arm a and is rotatively mounted in the upper wall of the camera-box. V designates the [inderspindle carrying at its upper end the [indersupporting plate V. U designates a pinion on the spindle U, V2 a gear-wheel on the spindle V, and V3 an intermediate pinion or idler intel-meshing with said pinion U and IOO IIO

said gear-wheel V2 and through which rotation of the shaft U is communicated to the shaft V. Said pinion U is adapted for rotation by means of a worm-shaft W, which is mounted in bearing-lugs w w on the inner face of the camera-box, and which shaft is adapted to project outside of thebox to be manually engaged by the operator. With this construction the finder-spindle may be rotated to any angular position desired and will be held in the adjusted position until purposely changed.
